# ADR: Nous Platform Scope

Status: Accepted  
Date: 2026-05-12

## Decision

`@nous/platform` is the model lifecycle and deployment registry surface for V2.
It owns model registry entries, deployment manifests, provider routing metadata,
cost-cap integration, and per-service evaluation pointers.

## Implementation Contract

Before any V2 AI service depends on `@nous/platform`, the package must expose:

- model registry CRUD
- deployment manifest validation
- provider routing metadata
- cost cap configuration
- evaluation result links
- audit export hooks for `@themis/accountability`

An empty package or barrel-only export is not acceptable.
